Additional Details

The 'PV' suffix in HD74HC273PV-E indicates a specific through-hole package, likely a DIP (Dual In-line Package). The 'E' likely refers to specific manufacturing or environmental standards. The propagation delay from the clock input to the output and from the clear input to the output are crucial timing characteristics. The setup and hold times for the D inputs must be considered for reliable data capture. The datasheet provided by Renesas includes detailed specifications, including timing diagrams, voltage levels, and temperature ranges.
